Subject: 2.6.21.5 BUG: USB FTDI FT323BM usb exports duplicate symbols
Date: Wed, 27 Jun 2007 16:05:23 +0200 [thread overview]
Message-ID: <46826EA3.2020707@anagramm.de> (raw)
Whenever I plug/unplug the FTDI FT232BM USB-RS232 converter, the latest
2.6.21.5 kernel complains:
usb 2-1: USB disconnect, address 7
ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0
ftdi_sio 2-1:1.0: device disconnected
usb 3-1: new full speed USB device using ohci_hcd and address 43
usb 3-1: configuration #1 chosen from 1 choice
ftdi_sio 3-1:1.0: FTDI USB Serial Device converter detected
drivers/usb/serial/ftdi_sio.c: Detected FT232BM
usb 3-1: FTDI USB Serial Device converter now attached to ttyUSB0
usbcore: exports duplicate symbol usb_buffer_unmap_sg (owned by kernel)
usbserial: exports duplicate symbol usb_serial_port_softint (owned by kernel)
kobject_add failed for ftdi_sio with -EEXIST, don't try to register things with the same name in the same directory.

Is this considered harmful?
Let me know if you need more debugging information.
